Figure 2: 650 eV-wide electron energy-loss spectra captured at each pixel produced this spectroscopic image of a lanthanum strontium manganate and strontium titanate (La0.7Sr0.3MnO3/SrTiO3) multilayer, showing the different chemical sublattices (from top, left to right): the lanthanum-manganese edge, the titanium-lanthanum edge, the manganese-lanthanum edge, and a false-color image formed by combining the rescaled Mn, La, and Ti images.

The group also used the array to image multiple point sources. Currently, the field of view achieved by the nanohole array is not compatible with practical imaging applications but future systems with more complex arrays could progress to larger FOVs for applications like microelectronics.

As nanotechnology, chemistry, and biotechnology advance, scientists will require imaging tools capable of ever better resolution. Techniques like SXDM, EELs, and nanohole array imaging offer paths to sub-wavelength imaging that will keep pace with technology demands.
